CLEANING DEVICE FOR GAS-COLLECTING MAIIil'S.

To all whom it may concern:

Be it known that I, LUDWIG CARL FLAG- oUs, a subject of the GermanEmperor, and resident of the borou h of Manhattan, city, county, andState of New York, have invented certain new and useful Improvements inCleaning Devices for Gas-Collecting Mains and the Like, of which thefollowing is a specification.

-My present invention relates to devices for removing from gas mains andthe like, impurities, such as tar, pitch, coal dust which may adhere tothe walls of such conduits.

The invention has been deviced for use more particularly in connectionwith thegas-collecting main of a coke-oven plant, but it will be evidentthat the new cleaning device may be used for other purposes also.

The invention involves the provision of a traveling mechanical cleaningdevice, such end view thereof, with parts in section; and

Fig. 3 is a detail plan view showing, in a diagrammatic fashion, the sixjuxtaposed runs of the three cleaning chains employed in the specificexample of my invention illustrated by the drawings.

In Figs. 1 and 2, A designates the collecting main which receives gas inthe usual manner, say from a coke oven pant, the gas P3551110 on fromthis ma n to any suitable plant for the recovery of by-products (notshown). It is well-known that in the course of time various impuritiescontained in the I gas will be deposited on the walls of the main,forming a gradually increasing sediment or crust which would clog up themain if allowed to row. Among such impurities I will mention sticky tar,pitch, and particles of coal dust. Hitherto such detrimental depositshave been knocked loose periodically by means of rods and thenretransverse plane, see Fig. 3. hold the chain runs in this relation,they are Specification of Letters Patent.

I moved, and it has also been attempted to wash the deposits away bymeans of very fluid tar, flowing at the bottom of the main. However,this is but partially successful, and it was still found necessary toscrape'the main from time to time, although at longer intervals. In thedrawing the inlet for the thin or fluid tar used as a cleaning liquid issupposed to be atthe right hand end of the main A, and at the lowerportion of each end or head there is a trough-shaped extension Bcommunicating with the ,body of the main, partitions B being provided ateach junction to preserve a seal by, dipping into the cleaning liquid C.One of the troughs B is provided with an overflow Cf forming an outletfor the liquid tar or like cleaning fluid, and preferably the bottom ofthe maln is inclined toward this outlet. A

suitable motor D is mounted on brackets at one end of the main A, and bymeans of a worm and worm wheel gearing D the motor drives a shaft Ecarrying a sprocket wheel E. A chain F transmits motion from thesprocket wheel E to another sprocket wheel G upon the outwardlyprojected portion of a shaft G whose main portion is within one of thetrough-shaped extensions B. In the example shown, three wheels G G G ofdifferent diameters are rigidly mounted on theshaft G in such a mannerthat the lower portion of each wheel dips into the liquid C, althoughthis is not absolutely necessary. These wheels are adapted to impart atraveling motion at different linear speeds, to movable scrapingelements which in the example shown consist of three chains H, H, H eachof which has both of its runs arranged close to the bottom of the main Aand lengthwise thereof, the six runs being therefore adjacent to eachother and in the same In order to guided by two sets of guides or-idlersJ (three idlers in each set) which are mounted independently on shaftsJ. At the (upper) end opposite to the shaft G is located a shaft K onwhich are mounted rigidlythree chain wheels K, K K corresponding in sizeand in arrangement to the driving chain wheels G G, G.

It will be seen from Fig. 3 that the six adjoining chain runs 'travelalternately-in opposite directions. Furthermore, owing to thedifi'erence in the size of the wheels G 'G',,G those chain runs whichtravel in the same direction will move at different rates of speed. Avery efiicient scraping action is thus obtained for the loosening of thesticky tar and other foreign matter tending to form incrustations on thewallsof themain A. The continuous stirring and scraping action willenable such foreign substances to be carried away readily by theliquidtar C or other cleaning fluid which overflows at the outlet C. Thedevice is mechanical, and continuous in its action, and the manual laborrequired hitherto for cleaning the main is dispensed. with. The liquidseal at B enables the trough-shaped extensions B to be left open at thetop, as shown, so that the chain wheels G, G, G and K, K*, K

and also the idle-11's J are readily accessible.

' Various modifications may be mith without departing'from the'nature'of my'invention as set forth in the. appended claims.

I claim:
